There’s nothing worse than sitting in your home and realizing that your air conditioner is blowing hot air--especially during the sickeningly hot summer months. Even though It’s not summer yet, you don’t want to look for answers for why your air conditioner isn’t working when you’re burning up inside your home. It’s best to know the reasons ahead of time so you’ll know how to avoid them or when to call a professional. So why is your AC blowing hot air? Here are 4 common reasons: Ok, this might be a huge “duh” but if you’re getting hot air, you might have accidentally flipped your thermostat to “heat” mode. It happens to all of us. If that’s the case, switch it back to “cool” and you’re good to go. Chances are, your thermostat is set to cool, and you’re still getting hot air. The cause could be a dirty evaporator coil caused by a dirty air filter. This keeps your air conditioner from properly cooling your home. You can change the filter, but you'll need a professional to clean the evaporator coil.

Walk outside and look at your air conditioner’s outside condenser unit. What do you see? Is there anything blocking the condenser coils air flow? ac unit in attic condensationAre they blocked with dirt and debris?home ac repair hammond la If so, this seriously impacts your air conditioner’s cooling ability.mini split ac units tampa Cleaning the condenser coils needs to be a regular activity during the summertime. This is the usual culprit. Your air conditioner needs a proper refrigerant (usually Freon) charge to cool your home. So a Freon leak can leave you feeling the heat since you’ll have a complete loss of cold air. You can tell if your air conditioner doesn't have enough Freon if ice forms on the inside and outside units.

Getting a Freon charge is best left to a professional. Keeping an eye on these problems will not only will this keep your air conditioner from blowing hot air, it will also prevent a costly breakdown. And the last thing you want is a breakdown during summer. So it only makes sense to get preventative maintenance done during the spring before it gets too hot.

you can hear the a/c compressor running and the fan motor is not turning.Because the compressor is running you know there is 220 volts power to the outdoor unit and you know the contactor is doing its job of delivering that 220 volts to the compressor and to the motor.  The malfunction will be a bad capacitor and/or a bad motor. Capacitors can be tested with multi-meters that have the ability to read microfarads or you can take your capacitor (and your motor) to your nearest U-FIX-IT store for a free bench test.  If the capacitor tests good then your motor is bad.Caution – Capacitors can store an electric charge (like a battery).  The shock hazard is non-lethal, but it is no fun.   Check the 220 volt power is off and discharge the capacitor by shorting between capacitor terminals (with insulated screwdriver) before removing the wires from the terminals.you cannot hear the a/c compressor running and the fan motor is not turning.  Your next troubleshooting step will be checking the 220 volt power because it is highly unlikely both the compressor and the fan motor would fail at the same time. 

Failure of the contactor (see picture above) most often produces this symptom.  You can prove the contactor is the problem by using a multi-meter or you can take your contactor to your nearest U-FIX-IT store for a free bench test.Testing the contactor on air conditioner outdoor unitCaution: use care when measuring live voltages not to touch bare connections or short them to the cabinet or to other terminals with the meter probes.Part Request Part Number or Description*Email* More From Jim PlummerJim is an ex-Air Force pilot and a business school graduate of University of Texas at Austin.
